What is The Isola IS580G PCB Material?
Isola IS580G halogen free laminates are designed with a high glass transition temperature (Tg 205°C), ensuring exceptional thermal stability in harsh operating environments. This means Isola IS580G maintains its structural integrity and mechanical properties significantly longer under thermal stress than standard FR-4 materials before transitioning to a rubbery state. This directly translates to enhanced reliability during operation and assembly. Isola IS580G offers a stable dielectric constant (Dk 3.80 @10GHz) and a low dissipation factor (Df 0.006 @10GHz), ensuring minimal heat generation during signal transmission, which is crucial for applications that require efficient performance in thermally challenging environments.
This laminate and prepreg products are manufactured with Isola’s high performance, low loss, multi-functional resin system, reinforced with electrical grade (E-glass) glass fabric. The unique resin system delivers a >25% improvement in Z-axis expansion while maintaining good flow and fill properties. These properties, coupled with superior moisture resistance at reflow, result in a halogen-free product with an industry leading combination of thermal and electrical performance.
Isola laminate is the ideal material for automotive, aerospace, networking, and computing applications where failure is not an option. The laminate from Isola represent a high performance solution engineered for applications that demand exceptional thermal stability, long term reliability, and compatibility with modern lead free assembly processes.
